(minimum requirement MacOS 10.11)

31.0.48 (8/22/2023)

1. Changed: Slovak translation updated (thanks Peter Lukáč).
2. Changed: The JRVR HDR to HDR tone mapping options are only shown if HDR pass-through is enabled.
3. Fixed: Solved a rare crash during import due to thread safety.
4. Changed: Non-editable fields no longer allow the checkbox to allow custom data in the Manage Library Fields dialog.
5. Changed: Added the option "Show only calculated fields" to Manage Library fields.
6. Changed: Playback of live TV in Transport Stream time-shifting mode will start a little delayed to reduce the chance of getting a black screen with audio only.

31.0.46 (8/18/2023)

1. NEW: Manual profile selection/overriding for JRVR, on a per-file basis. Available in the context menu, the playback OSD, and MCC.
2. Changed: Non-editable fields no longer allow the checkbox to allow custom data in the Manage Library Fields dialog.
3. Changed: Added the option "Show only calculated fields" to Manage Library fields.
4. Changed: Playback of live TV in Transport Stream time-shifting mode will start a little delayed to reduce the chance of getting a black screen with audio only.
5. Fixed: Radio Paradise didn't play when reliably when connected to a library server.
6. NEW: (Panel) Added options to the Advanced settings page to show/hide the fixed buttons on the main page, such as Streaming, Cloudplay, etc.
7. Changed: The bookmark is only cleared when pressing stop again if it's done within five seconds of the previous stop.
8. Changed: When tagging EXIF in images, empty field values will cause the corresponding EXIF tags to be removed, instead of setting the tag value offset to NULL.
9. Fixed: When renaming a value in a pane, if something with a semi-colon was entered the selection would reset (instead of selecting the first item in the new list).
10. Changed: Tagging of EXIF datetime tags will use format "yyyy:MM:dd 00:00:00" for dates without time, instead of "yyyy:MM:dd   :  :  " so that Google Photos will recognize it.

31.0.43 (8/7/2023)

1. Changed: When a smartlist finds no matches, a message is shown in the list.
2. Changed: Expressions that output an average use three decimal places instead of one.
3. Changed: Added "Favorites" category for Cloudplay in Theater View.
4. Fixed: MCWS Playback/Info when called early was creating the playback engine because of a recent change (31.0.29). Could cause crashes in MacOS (for example when JRemote was starting playback on a remote zone).

31.0.42 (8/3/2023)

1. Fixed: Backup and library connection issues caused by the [] fix in build 41.
2. NEW: Added a 44.1k auto configuration test for odd bluetooth devices that only work on 44.1k.
3. Changed: Clicking an empty checkbox field with multiple selections now changes based on the selected item (was using the first item instead).

31.0.41 (8/1/2023)

1. NEW: Added memory usage and open file handles to Reporter.
2. Fixed: Paired square brackets [] in a folder path prevented import of items in that path.
3. Changed: Removed the drive performance tests from Reporter.

31.0.38 (7/24/2023)

1. Fixed: Local CUSTOMIZATION RESOURCES (like modified FileAssociations.xml) were not being read from the Appdata tree (~/Library/Application Support/J River/Media Center 31/Data/Custom Resources/).
2. Fixed: Some crashes on particular versions of MacOS caused by differences in the Apple API for the browser that weren't being handled.
3. Fixed: Seeking with JRVR could result in some playback glitches since 31.0.35.
4. Changed: Updated Czech translation (thanks Jan Boháč).
5. Changed: Put the playing album at the top during a shuffle albums.
1. NEW: Added New, Popular, and Users categories for Cloudplay Playlists in Theater View.

31.0.36 (7/20/2023)

1. Fixed: Logging the playback information could lead to crashes in some cases.
2. NEW: Added "Shuffle Albums" to the shuffle menu to keep albums in track order but shuffle the collection of albums.
3. Changed: DSP Studio will be closed when shutting the program down to server mode.
4. Changed: More tuning of the Swap and Unswap expressions.
5. Changed: When clearing playing now, the menu option would enter the MRU list, but then keep working on the cleared zone.  So if you switched zones and picked the MRU, it was a little confusing.  Now it switches.
6. Changed: Made the default for logging to reset after 10 MB instead of to keep everything.
7. Changed: Reworked JPEG rotation so it uses the new EXIF code (testing appreciated).
8. NEW: Support reading and saving EXIF Artist and Copyright fields for images.  These fields will be saved in corresponding image EXIF tags if they only contain ASCII characters (since the corresponding EXIF tags only support ASCII).
9. Fixed: Thumbnail image embedded in an image might not be loaded because the EXIF tagging had a wrong thumbnail data size.
10. NEW: EXIF tags DateTimeDigitized and DateTime can be read into the library if custom fields "DateTimeDigitized" and "DateTime" have been created.
11. Changed: Slovak translation updated (thanks Peter Lukáč).
12. Fixed: Video playback could offset the playback position slightly after seeking.

31.0.34 (7/11/2023)

1. Fixed: Crash on MacOS 10.11 when initializing the web engine on startup.
2. Fixed: Parameterless file: URL's weren't being handled after the change to create background colors for web pages. Mostly affected trackinfos.

31.0.33 (7/11/2023)

1 NEW: Support reading and saving EXIF Artist and Copyright fields for images.  These fields will be saved in corresponding image EXIF tags if they only contain ASCII characters (since the corresponding EXIF tags only support ASCII).
2. Fixed: Thumbnail image embedded in an image might not be loaded because the EXIF tagging had a wrong thumbnail data size.
3. Changed: Improved reporting of DSD to PCM conversion in Audio Path.
4. Changed: More work on the Unswap expression.
5. Fixed: Parsing EXIF blocks could enter an endless loop with some images.
6. NEW: The Comment field (if not empty) will be saved in image EXIF tag UserComment.  The Name field will be saved to image EXIF tag ImageDescription if the text is ASCII, otherwise we try to save it into UserComment if UserComment is not already filled.
7. Fixed: Erroneous GPS data was loaded for some images taken with cameras not equipped with GPS.
8. Changed: Better support for commas without spaces in the Unswap expression.
9. Fixed: Improved state tracking during JRVR startup for a potential hang fix.

11. Changed: Unswap(...) handles double (and more) spaces just like Swap(...).
12. Changed: Updated libplacebo in JRVR, with many HDR gamut mapping improvements.
13. NEW: Added an option to JRVR Advanced settings to allow disabling the histogram in peak detection for improved performance on slow systems.
14. Changed: Drives&Devices, Playlists, Podcasts, Services&Plugins, and Streaming pages use skin background and text colors.
15. Changed: Reworked how the default webpages like Playlists, Drives & Devices, etc. are included (please report any issues).
16. Changed: A little work on the Unswap(...) expression to better support the new Swap(...) expression.
17. Fixed: Video playback could crash in some cases.
18. NEW: Added a setting to control the target contrast when tone mapping HDR to SDR in JRVR.

2. Fixed: Media Center could leak memory when parsing an invalid MP4 file.
3. Fixed: Spotlight was not loading properly.
4. Fixed: Double spaces are removed by the Swap(...) function to avoid problems they cause.

8. Changed: Updated Simplified Chinese translation (thanks YanJun Sun).
9. Fixed: The new formatted flag on Playback/Info was not working properly.
10. Changed: Slightly better handling of commas in the Swap(...) expression.
11. Changed: Tuned the Swap(...) expression based on feedback on Interact.
12. Changed: Updated libplacebo with a lot of tone mapping and gamut mapping changes for processing HDR videos in JRVR.

22. Changed: Tuned the Swap(...) expression function to work better with big strings.
23. Changed: Cleaned up the escapement in the Base URL of the links dialog so it should not be necessary (but the search expression still needs escapement).
24. NEW: Added mode to the MCWS Playback/Position and allow passing a percentage (works with relative or absolute seeks).
25. Changed: The "Unlock All Tabs" menu option disables when all the tabs are unlocked.
26. Changed: The "Lock All Tabs" menu option disables when all the tabs are already locked.

Playback of MKV files with Dolby TrueHD audio has major problems. Both video and audio are heavily corrupted. I'm not sure when this problem originated as I have not played TrueHD audio for sometime. There was no problem a few months ago. This is on a Mac Studio computer with the latest OS.

This is probably fixed in the next build already. I'll ask bob about posting one.
